Compass/Mini-Trip Computer Displaying SC
- Disconnect ambient temperature sensor connector. Sensor has a 2-pin connector with a Black/Light Blue wire and a Violet/Light Green wire and is located behind right center of front bumper. Turn ignition on. Observe Compass/Mini-Trip Computer (CMTC) display. If CMTC displays OC, replace ambient temperature sensor. If CMTC does not display OC, go to next step.
- Turn ignition off. Disconnect CMTC connector located behind overhead console. Measure resistance between terminals No. 2 (Black/Light Blue wire) and No. 5 (Violet/Light Green wire) at CMTC connector. If resistance is less than 1000 ohms, Violet/Light Green wire is shorted to Black/Light Blue wire. Repair wiring as necessary. If resistance is 1000 ohms or more, go to next step.
- Measure resistance between ground and terminal No. 5 (Violet/Light Green wire) at CMTC connector. If resistance is less than 5 ohms, repair short to ground in Violet/Light Green wire between CMTC and ambient temperature sensor. If resistance is 5 ohms or more, replace CMTC.
